the format in which to export data
an array containing which columns of model will be exported, or null for all columns
an array containing which rows of model will be exported, or null for all rows
list of options for the export
a new string, use glib.global.gfree when no longer needed
Exports data contained in model to a string; the format is specified using the format argument, see the gda.data_model.DataModel.exportToFile documentation for more information about the options argument (except for the "OVERWRITE" option).
Warning: this function uses a #GdaDataModelIter iterator, and if model does not offer a random access (check using gda.data_model.DataModel.getAccessFlags), the iterator will be the same as normally used to access data in model previously to calling this method, and this iterator will be moved (point to another row).
